. of its movement, anothe wouldbe very difficult to assemble the sash plate onto the regulator as is necessary on the job. The custom is to ist attach the regulator to the loclr board and foot board and then the windows are often put in after the job has been trimmed and painted. lt is necessary then to drop them down through the top slot of the windo-w well, and there must be' some reliable way of finding and holding the pin so as to slip the sash plate in' place, The saddle that l have designed accomplishes this purpose, as the major 'plate drops clear down over the side of the drum as shown in Fig. 5, while the rolls ride over the top of the drum. The flange n on the periphery of the drum rides in between the major plate and the rolls'. f' This causes the saddle to ride the flange and notthe cable and hence, relieves the cable of the weight of the sash. This is a very important point as it makes the cable of sufficiently long life to be practical.

Obviously,rthe large amount of plate at the side of the drum and the flange n will prevent the rolls from twisting off the top of the drum. This serves to anchor the pin from retreating from the sash plate as the sash plate is pushed down into the. window well to locate the pin in the sash plate slot, shown in Fig. 4.

, lith the saddleY having i a large portion of tlielpla-te abutting directly against the drum,

considerable chattering and rattling might take place, but to avoid this l use a bowed spring o which is looped over the metal plate between two pairs of struck out lugs g. This takes talres up any looseness and prevents chattering.

Secured to the top of the lregulator plate 7' is a stop pin s. This stops the saddle after the pin has slightly passed the vertical center line of the drum. The consequencel` is that in this position, the regula-tor is locked froniany actuation originating with the sash, as obviously the saddle cannot force the pin and this is theonly way the drum can be turned by such actuation after the saddle has passed the vertical center line. `When the sash reaches the downward limit stop t which is an integral part ofthe pulley-carrying yoke u stops the sash plate.

AllVhat T claim is:

l. ln a window regulator, the combination of a drum provided with a flange a; its outer end, a cable ruiming over the drum, and a saddleA anchored to the cable and larranged, to carry the window panel, the

, said saddle riding only over this one flange and Yvided with means `for lreei'iiiig1 it infiipriglit position tov relieve the cable .from

undue. abrasion and wear.4

-ln a` windowregulator, sa @i in: which the draft member runs, and a flangetlie combinaber, a hanged drum over riding saddle provided with 'a plate portion depending down the side of the drum when the saddle runs over the drum to prevent rocking of the saddle downwardly beyond a. given limit.

3. ln a window regulator, the combination of a draft member, a flanged drum over which the draft member runs, and a flangeriding` saddle for the window comprising` a plate anchored at its top to the draft meniber and having a portion thatV depends over tie side of the drum when the saddle runs over the drum, said plate being provided with an outwardly projecting window-supporting pin.

Tn a window regulator, the combination of a draft member, a flanged drum oier which the draftmember winds, Vand a {langeriding saddle providedwith Va: plate'portion that projects over the side of the drum vclamped to the plate,-and a window support# ing pin carried by the plate.

G. ln a window regulator, the 'combination of a draft member, a drum over which the draft member runs, and a saddle coiiiprisiiig a major plate provided wit-h a turned-iii plural-notched ange at the top, a pair of rolls supported on the platethe draft member being` looped around the rolls and over the intervening web between, the notches of thefflange, and a window-supporting pin carried by the plate.

7. .ln a window regulator, the combination of a cablea drum about which the cable winds, and a saddle provided with a depending` plate portion engaging the side of the drum when the same passes over the drum, and a spring on the plate for engaging the drum to prevent rattling between the two members.

8. In a window regulator, the combination of a cable, a flanged drum over which the cable runs, and a saddle provided at its top with means for clamping the cable i'n place and arranged to ride normally only on the flange of the drum in passing over the drum.

9.

l0. In a Window regulator, the combination of a cable, a flanged drum over which the cable runs, and a saddle provided with a major plate provided With an upper flange having a pair of notches, a pair of rolls provided with studs supported by the major plate, a minor plate clamped to the end of the rolls, the cable being turned over the rolls and looped through the notches in the ange, and a Window-supporting pin carried by the major plate.

11. In a Window regulator, the combination of a top regulator plate provided With a stop pin, a drum rotatablyT supported upon the plate, a second rotatable member supported below such plate, a draft member running over the drum and over such second rotatable member, a stop adjacent said seoond rotatable member, and a Window-sup porting member or saddle Carried on the draft member and stopped in its turning movement on the drum by the stop pin and stopped at the lovver end of its movement by the stop located adjacent the second rotatable member.

In testimony whereof he has affixed his Signature. v
